Type 347 stainless is an austenitic steel alloy with added Niobium/Columbium which acts as a stabiliser. The alloy is, therefore, suitable for service in aqueous and low-temperature environments as the alloy has good resistance to intergranular attack.
The alloy also offers good resistance to polythionic acid stress corrosion cracking and is a useful material for use around reactor plants. Type 347 is non-magnetic in the annealed condition and can only be hardened by cold working. The alloy finds use in the oil, gas and chemical sector as well as the nuclear industry.
Type 347 stainless steel is classed as a multi-purpose austenitic stainless steel - the alloy offers excellent heat and corrosion resistance. The material has better mechanical properties than 304, which makes the alloy more suitable for high-temperature service.
Commercial applications for this engineering material include:
